I am confused why you are trying to achieve an etch finish???I am not sure I even know what that is.Marble either has a honed finish or a polished finish period that's it.No coating should be put on marble at all no crystalizer no wax no acrylic nothing.
 
If you are after a honed finish which would be matte with no clarity or very little and then color enhance to get some color to the stone.If the floor is flat you could achieve this very quickly with some diamond abrasives,if the floor is not flat it would have to be ground flat first with metals otherwise all your frames will be shiny still.
 
If you can get us some pics that would help alot,

I have a client that has a marble in her master bath on the floor & vanity with a finish I have not been able to reproduce. The tile are 12x12, marble, bone color, very little marble pattern, what looks to me like fossils white in color, and some small short  green veins. Customer said it came from Arizona Tile about 10 years ago. They have no record and no one known’s the name of the stone. Here’s my problem the tile has a finish that looks like an acid etch, with a slight polish, and enhanced. I say it looks like an etch finish because it feels pitted. The closet finish I could find on marble is tumbled.  I’ve tried to duplicate the finish by removing the finish by etching with Phosphoric acid, CLR, concrete etcher, and Vinegar but haven’t been able to remove  enough surface to get the texture I’m looking for.  Has anyone seen a similar finish on marble? Is there a specific acid to get a etched finish? Is there a brush or other tool I could use? I think this is the second marble job in 2 years, we mostly do Saltillo, Sandstone & Travertine ……  Any help would be greatly appreciated !

 

Thanks,
